CANNING APPARATUS.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed August-8. 1906. Serial No. 329,744.

To all whom 'it may concern:

Be it known that 1, NOAH W. THARP, a citizen of the United States,residing at Elkin, in the county of Surry and State of North Carolina,have invented certain new and useful Improvements in Canning Apparatus,of which the following is a specification.

My invention relates to improvements in canning apparatus, and has forits object, the provision of a simple and inexpensive device of thischaracter which may be utilized for canning and preserving processes andwhich will be thoroughly practical and efiicient in every particular.

Another object of the invention is the provision of an apparatus of thischaracter which may be used for a variety of purposes where a boilingprocess is required, which is portable, and may be used equally as wellon an ordinary kitchen stove as upon a furnace.

To attain the desired objects, my invention consists of a tank, aheating compartment entirely surrounding the lower portion of the tank,and fines passing through the tank, said flues in communication with theheating compartment My invention further consists of a boiler andcanning apparatus embodying certain other novel features ofconstruction, combination and arrangement of parts, substantially asherein specified.

Figure 1, is a horizontal sectional view of the device taken through theheating chamber and fines, looking downward Fig. 2, is a longitudinalvertical sectional view showing my improved canning apparatus mountedfor use on an ordinary furnace.

In the drawings: the numeral lfdesignates the tank of the apparatus,adapted to holdwater and to contain the products to be treated. Entirelysurrounding the lower portion of the tank and on a level with the loweredge thereof, is a heating compartment or chamber 2, which is widened atthe rear end of the tank and provided with an outlet stack 3. A slide 4,retained in guiding cleats 5, closes an opening 6, in the bottom of theheating chamber directly under the stack, and this slide serves toregulate the draft in the stack, or to allow cleaning of the stack.

Extending upward through the bottom of the tank near the rear endthereof, are a plurality of short pipe sections 7, which by means of theelbows 8, are con nected to the longitudinal flues 9, which are horizontally disposed in the tank andjpass through the front wall thereof.These fines are thus in direct communication with the heat compartmentat the front end of the tank, and a dividing partition 10, is placed midway in this portion of the heating chamber at the front end of the tank.Openings 11, are formed in the outer wall of the heat compartment inalinement with the flues in the tank, and a slide 12, provided withcomplementary openings 13, issecured in guideways 14, so as to form aclosure to the openings in the heat chamber. By means of this slide, asthe openings in the slide are in alinement with the flues, these fluesmay be readily cleaned at any time. At the lower corners of theapparatus, are provided the depending corner extensions or lugs 15,which are adapted to engage the corners of the stove or furnace tosecure the device in position upon the stove.

When used in connection with an ordinary brick furnace, the tank isplaced directly upon the open top of the furnace with the tank flues indirect communication with the fire box. With both of the draft slidesclosed, the only course open to the products of coinbustion is asfollows: The heat passes up through the pipes in the bottom of the watertank, thence through the horizontal lines to the heat compartment at thefront end of the tank. Here it is diverted by the dividing partition andcaused to flow through the chambers along the sides of the tank, back tothe rear of the chamber and thence to the stack. During this passagemost of the heat is given up to the Water in the tank and the water isconstantly kept at the desired temperature. The draft may be increasedby opening the slide at the foot of the stack, so that the degree ofheat may be regulated at will.

When it is desired to cook tomatoes, beans or like products, a falsebottom 18, provided with suitable handles 19, may be placed in the tankresting upon the flues, and the products placed upon the said falsebottom.

By causing the products of combustion to circulate both through andaround the water tank, the water is quickly heated and maintained at thesame even temperature without any waste of fuel. The apparatus may beused equally as well in connection with an ordinary cooking stove, bymounting the apparatus upon the stove with the fines in connection withthe fire, and the stack connected with the chimney. The apparatus mayalso be used for boiling clothes or in fact in any place where aconstant heat is required.

From the above description taken in connection with the drawings it willbe evident that I have accomplished all the objects herein set forth,and have produced a boiler or canning apparatus which is economical ofproduction and operation.

I claim:

1. A canning apparatus comprising a tank, a heating compartment entirelysurrounding the lower portion of the tank, a stack mounted on saidcompartment, a damper slide in thc bottom of the compartment beneath themouth of the stack, flues extending up through the bottom of the tankand laterally the full length of the tank to the compartnient at theforward end thereof, there being openings formed in the front wall ofthe compartment in alinement with the flue exit openings, a partition inthe compartment between said openings and a damper'to close saidopenings.

2. A canning apparatus comprising a tank, a heating compartmentcompletely surrounding the lower portion of said tank, an outlet stackto the compartment, a damper slide in the bottom of the compartmentbeneath the mouth of the stack, fiues extending up through the bottom ofthe tank and directed laterally the full length of the tank to thecompartment at the forward end thereof, a deflecting partition locatedin the front portion of the heating chamber adjacent and between theflue exit openings, there'bespecification in the presence of twosubscribing witnesses.
